Specification of Letters Patent.

icatented May-22, 1906.

T0 all whom, t may concern.-

Be it known that we, THOMAS LEGGETT STURTEVANT, residing at Quincy, and

THOMAS JOSEPH STURTEVANT, residing atI Wellesley, in the county of Norfolk and State of Massachusetts, citizens of the United States, have invented or discovered certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to that class of lubricators or oiling devices provided with a plurality of outlets which are to be connected with the several parts of a machine or engine to be lubricated; and the invention has for its object to provide a lubricator of the class referred to by means of which the oil which is fed or admitted .to the lubricator may be evenly distributed to the several outlets, so that there will be an unfailing supply of the lubricant to all of the various parts oi the nachine or engine connected with said outets.

To this end the invention comprises a revolving or otherwise moving distributer which receives the incoming lubricant and distributes the same to the several outlets of the lubricator, as will hereinafter more fully appear.

In the accompanying drawings, Figure 1 is a vertical section ofv a lubricator embodying the present invention, and Fig. 2 is a top or plan view thereof. Fig. 3 is a section of the same on line 3 3, Fig. 1; and Fig. 4 a Section on line 4 4, Fig. 1. Fig. 5 is a detail view to show the crank connection of the pump cross-head.

Referring to the drawings, 12 denotes the base or cup portion of the lubricator, the same being provided with a circular series of pockets 13, each of which has an outlet 14, which in practice will be connected by a suitable pipe or tube with a part of the machine or engine to be lubricated. The cup 12 has in the construction herein shown a screwthreaded connection with a metal framepiece 15, which affords a bearing for a driving-shaft 16, provided with a beveled gear 17, which drives the rotary distributer and the pump.

In the form of the invention herein illustrated the rotary distributer comprises a bevel-gear 18, meshing with the bevel-gear 17, and rigid or integral with the said bevel-gear 18 is a conical distributer proper, 19, which is preferably provided with a series of grooves 20, discharging into the pockets 13 of the cup 12, The rotary distributer 19 is journaled on a stud 21, 'fixed to the base of the cup 12.

The lubricator will preferably comprise an air-tight chamber communicating with a suitable compressed-air supply or with a supply of gases under pressure taken from the cylinder of a gas-engine or otherwise, and to this end the upper portion of the chamber will preferably consist of a glass cylinder 22, interposed between the frame-piece 15 and the top plate 23, packing-rings 24 at the top and bottom of the said glass cylinder being preferably provided to make air-tight oints. The said top plate 23 is connected'with the frame-piece 15 by screw-bolts 25, herein shown as being tapped in lugs or parts of said part 15. Air under pressure may be admitted to the chamber of the lubricator for the purpose of forcing out the oil through a pipe or tube 26, opening into said chamber and provided with a cock 27, which may be turned to close the said air pipe or tube when desired.

The oil-inlet portion of the lubricator in the construction herein shown comprises a block 28, mounted on the top plate 23 and provided with an oil-inlet 29, communicating with a chamber 30, in which is located a ballvalve 31. The chamber 30 communicates by a passage32 with a pump-cylinder chamber 33, in which works a piston 34, provided with a cross-head 35, receiving a crank-pin 36 on the bevel gear-wheel 17. The pump-cylinder communicates with a chamber 37, provided with a ball-valve 38, said chamber 37 in turn communicating with a feedpassage 39, preferably terminating within the chamber of the lubricator in a tube 40, arranged above, but separated from, a feed-tube 41 to afford a sight-feed, the said tube 41 discharging into the distributer. The pum just described will force the incoming oi into the chamber of the lubricator against the air or other iiuid-pressure therein if there be such pressure within the said chamber; but said pump need not necessarily be employed if the IOO oil be fed to the lubricator simply by gravity from an oil-tank placed above said lubricator or on a higher level than the same. In such case oil may be admitted to the chamber of the lubricator through an inlet 42 near the top of the block 28.

In the construction herein shown the bevel- -'gear 18 is recessed at its top to afford a small oil-receiving cup, from which through ducts 43 the oil can pass to the distributing-cone 19 beloW, and although this is the preferred form of the invention the latter is not to be understood as being limited thereto, as the oil might be distributed directly from the cupped bevel-gear 18 into the pockets 13, or the rotary distributer might consist of a fiat plate or table onto Which the oil might be fed and from Which the oil might be discharged by centrifugal action against the inner Wall of the cup 12, so as to run down into the receivingpockets 13. It will also be understood that if the oil be fed to the chamber of the lubricator by gravity through the inlet 42 and no Huidpressure be employed Within the chamber the force-feed. pump might be omitted altogether, and the details of the invention may be otherwise varied Without departing from the spirit of the invention. rI he single forcepump serves in coperat-ion with the fluidpressure Within the chamber of the lubricator to force the lubricant through the several outlets, While the sight-feed always shows Whether or not the pump be properly Working, and if at any time it should not be properly Working the air or gas pressure can be shut oif by the cock 27 and oil be admitted by gravity through the inlet 42.

Having thus described our invention, We claim and desire to secure byLetters Patent- 1, In a lubricator, the combination with an inclosed chamber provided With a suitable inlet and with a series. of oil receptacles or pockets each of which has an outlet, of
